How was the Universe made?

Most of the satronomers think that the Universe was formed during an even called “BIG BANG” – a giant explosion which occurred between 10 to 20 billion years ago. During the Big Bang all of  the space, time, matter and energy in the Universe was created. This giant explosion hurled matter in all directions and caused space itself to expand. As the universe cooled, the material in it combined to form galaxies, stars and planets.

      The Universe is made up of billions of galaxies. In the Universe, there are 2,000,000,000,000,0000,000 stars. These stars made up galaxies. Each galaxy has a billion of stars. The Universe is incredibly huge. It would take a modern jet fighter more than a million years to reach the nearest star to the sun. Travelling at the speed of light (300,000km per second), it would take 100,000 years to cross our Milky Way galaxy alone.

        No one knows the exact size of the Universe, because we cannot see the edge. All we do know is that the visible Universe is at least 93 billion light years across (A light year is the distance light travels in one year – about 9 trillion km).

What is a comet?

Comets are basically dusty snowballs which orbit the sun. They are made of ices, such as water, carbon dioxide, ammonia and methane, mixed with dust. These materials came from the time when the solar system was formed. Comets have an icy center (nucleus) surrounded by a large cloud of gas and dust (called the coma). The coma is created as the ice in the nucleus is warmed by the sun and vaporizes. Comets can develop 2 tails as they travel closer to the sun, a straight gas tail and a curved dust tail. The gas tail is created by the solar wind, whose magnetic fields pull the gas away from the comet's coma. The dust in the coma is not affected by magnetic fields but is vaporized by the sun's heat, and forms a curved tail which follows the comet's orbit.

Another member of Solar System - Asteroid

The asteroid belt lies between the planets Mars and Jupiter. It contains lumps of rock and metal much smaller than planets. These lumps are called asteroids or minor planets. Asteroid like other planets moves around the sun in its band area. They are not visible from Earth with the naked eye, but many may be seen through binoculars or small telescopes.
